ABSTRACT:
A combustion or partial oxidation process for using an oxidant with a low nitrogen concentration. An oxygen-containing gas is introduced into an ion transport module including an ion transport membrane having a retentate side with a first pressure and a permeate side with a second pressure to separate a purified oxygen gas stream on the permeate side and correspondingly depleting the oxygen on the retentate side to produce the oxygen-depleted gas stream. A purge gas stream containing a low concentration of nitrogen is passed to the permeate side to form an oxidant stream containing less than about 40% oxygen. The oxidant stream and a fuel are then introduced into a combustion or reaction chamber to produce heat and products of combustion or partial oxidation.
